“One of the most commonly noted constraints of the JIF is its calculation as a mean. This mode of data repre-
sentation has the potential limitation of a small number of highly cited manuscripts disproportionately influenc- Daugherty et al.
ing the JIF. Therefore, if the number of citations per article is a skewed distribution, a metric based on a calcu- [1]
lation of a mean could render an evaluation that is not representative of the majority of the articles included in
the calculation.”
“The other most commonly described constraint of the JIF is an aggregate index encompassing many different Daugherty et al.
types of publications that include not only original research articles but also reviews, guidelines, and state- [1]
ments, which have higher citation metrics.”
“For example, a journal (A) scored almost a double increase in its IF during just 4 years. It turned out that in a
review published in another journal (B), out of 490 references 445 were citations of articles published by jour-
nal A and all of them during 2 years from which the journal’s IF was calculated. Incidentally, three of the four Górski et al. [2]
authors of that review were on the editorial board of journal A. While self-citations are very easy to identify, ci-
tation cartels are difficult to track and can do the most harm to scientometrics based on manipulated data.”
“In view of the above, we can conclude that the evaluation of the quality of publications based exclusively on Salamanca
the impact of the journal in which the article was published is, in addition to being imprecise, unfair in the case Castro [5]
of the nursing discipline, given the limited possibility of publishing in this type of journal for our group.”
“Although the JIF refers to a journal as a whole and says nothing about the influence or even the scientific
quality of individual articles, it is often used to assess the research performance of scientists. This is not the only Open Access
reason why the JIF is often criticized. It is also highly dependent on the subject area and thus not comparable Network [4]
across disciplines; in addition, it only takes into account the past two years in each case. The calculation is not
very transparent and often not independently reproducible.”
“To be able to cite journals by rank, JIFs are given to three decimal places and without confidence intervals or University of
error bars. However, this data accuracy is an illusion. Measuring citation counts is not an exact science, as has Zurich [7]
been shown in several examples in bibliometrics, e.g., Vanclay, 2012.”
